Using these lamps is a breeze. First, find a suitable spot in your home or commercial space. Just plug them in, and use the 3 - way switch to adjust the light as you like. Since no assembly is needed, you can start using them right away. When it comes to bulbs, use an E26/Medium base bulb, and replacing it is easy when the time comes. For maintenance, simply dust the glass base and the shades regularly with a soft cloth. Keep them away from harsh chemicals as they may damage the glass or the shade. Enjoy the beautiful, soothing light these lamps provide for a long time.
